The HVAC guy said he could do blown in fiberglass of some sort (no
formaldehyde, he claims) on the attic floor before they install the
ductwork. When I mentioned cellulose, he didn't seem to like that
idea. He seemed to think that with my allergies, it might be an
issue. I'd certainly rather breathe cellulose than fiberglass. Of
course, if the ducts are sealed as well as they should be, there
shouldn't be ANY leakage into the house. Working up there in loose
fiberglass would not be pleasant should we need to do that.
Problem is, it doesn't cool down at night here, or doesn't
consistently. It's 9 pm now, and it's still over 90-degrees. We are
frugal with the AC, but do need it.
I understand about the proper sizing. Our former house was never
comfortable because of that. We're going to ask the guy if this unit
he's recommended can be downsized a bit since we will be adding so
much insulation.
